Autism spectrum disorders (ASDs) are common, heritable neurodevelopmental conditions. The genetic architecture of ASDs is complex, requiring large samples to overcome heterogeneity. Here we broaden coverage and sample size relative to other studies of ASDs by using Affymetrix 10K SNP arrays and 1,181 [corrected] families with at least two affected(More)
We describe a patient with autism and brachymetaphalangy, meeting criteria for 2q37 deletion syndrome (also called Albright Hereditary Osteodystrophy-like syndrome or Brachydactyly-Mental Retardation syndrome, OMIM 600430). Our molecular cytogenetic studies, including array comparative genomic hybridization (aCGH) and fluorescence in situ hybridization(More)
With the completion of the human genome sequence the functional analysis and characterization of the encoded proteins has become the next urging challenge in the post-genome era. The lack of comprehensive ORFeome resources has thus far hampered systematic applications by protein gain-of-function analysis. Gene and ORF coverage with full-length ORF clones(More)
Cisplatin is a widely used chemotherapeutic agent. Here we show that cisplatin induces apoptosis in renal collecting duct-derived cells (MDCK-C7 cells, resembling principal cells) in a dose-dependent manner. Additionally, we studied the role of mitochondria in this process by inhibition of the mitochondrial respiratory chain, the F1F(o)-ATP synthase or by(More)
Ochratoxin A (OTA) is a potent nephrotoxin and suspected to be involved in the etiology of Balkan endemic nephropathy. Nanomolar concentrations of this mycotoxin induce apoptosis in renal collecting duct-derived cells (MDCK-C7 cells, resembling principal cells). We studied the role of mitochondria in this process by inhibition of the mitochondrial(More)
BACKGROUND Nephrotoxic substances like cisplatin or ochratoxin A (OTA) induce cell death in human proximal tubule-derived cells (IHKE cells). Mitochondria play a significant role in apoptosis and loss of their function may influence OTA- or cisplatin-induced apoptosis. Extracellular pH also plays an important role in tumor genesis. Therefore, we(More)
The epidermal growth factor (EGF) regulates cell proliferation, differentiation, and ion transport using ERK1/2 as a downstream effector. Furthermore, the EGF receptor (EGFR) is involved in signaling by G-protein-coupled receptors, growth hormone, and cytokines via transactivation. It has been suggested that steroids interact with peptide hormones.(More)
The steroid hormone aldosterone plays an important role during pathological tissue modifications, similar to cardiovascular or renal fibrosis. The underlying mechanisms for the pathological actions are not understood. Interaction of aldosterone with the epidermal growth factor (EGF) receptor is an attractive hypothesis to explain pathological tissue(More)
